| A relative of mine is trying to restore an old (17th century!) boat used in our area which could sail either way...they simply used to change the rudder and put it at the other end to sail in a different direction (because they used to work in narrow canals) it's called ´amphidrone' in French and we need to know whatever it's called on English to exchange with various muséums around the world. Any idea what this would be called? |

I think the nearest translation would be "double-ended boat" ------------- |

| Same name: amphidrome. From Greek - amphi - both, of both kinds, on both sides. And Greek - dromos - course (running). |

| Yeah, I'm not aware of a specific tech term. Possibly amphidrome was made up by the designer. |

I think there are proas in the pacific that work like this? Like a trimaran with an ama missing. I think the outrigger is a weight to windward rather than a float to leeward? But not sure about that the more I think about it. Never seen one in the solent, so may be a myth....

there are Proas which shunt rather than tack or gybe... maybe call it a 'shunter' http://www.youtube.com/watch?v=VnkRpblVD6E" rel="nofollow - http://www.youtube.com/watch?v=VnkRpblVD6E

An interesting project that stirred a memory. Not sure if this will be helpful but it seems vaguely similar. In one of Patrick O'Brians novels there is a ship called the HMS Polychrest. It had a bow at either end, lifting keels and I'm sure it had the ability to sail in either direction. Patrick O'Brian usually used historical sources as the basis for his fictional ships. So I had a dig around, it transpires that the Polychrest was probably based on the real life "HMS Project". It had 2 sharp ends and a rudder at either end.  It may give you something to google.

Most of us will have been on one or seen one as many ferries are double ended.  ------------- |

| Changing the rudder to the other end - it's a Proa. Not an English word...but used in English descriptions of South Sea vessels. |
